Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
ahmad:9441 – Makkī b. Ibrāhīm > ʿAbdullāh / Ibn Saʿīd b. Abū Hind > Ismāʿīl b. Abū Ḥakīm a freed slave of Āl al-Zubayr > Saʿīd Ibn Marjānah > Abū Hurayrah

If anyone emancipates a Muslim slave, Allah will set free from Hell an organ of his body for every organ of his (slave's) body. (Using translation from Muslim 1509a)  

أحمد:٩٤٤١ – حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ حَدَّثَنَا عَبْدُ اللهِ يَعْنِي ابْنَ سَعِيدِ بْنِ أَبِي هِنْدٍ عَنْ إِسْمَاعِيلَ بْنِ أَبِي حَكِيمٍ مَوْلَى آلِ الزُّبَيْرِ عَنْ سَعِيدِ ابْنِ مَرْجَانَةَ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ

قَالَ رَسُولُ اللهِ ﷺ مَنْ أَعْتَقَ رَقَبَةً مُؤْمِنَةً أَعْتَقَ اللهُ بِكُلِّ إِرْبٍ مِنْهُا إِرْبًا مِنْهُ مِنَ النَّارِ حَتَّى أَنَّهُ لَيَعْتِقُ بِالْيَدِ الْيَدَ وَبِالرِّجْلِ الرِّجْلَ وَبِالْفَرْجِ الْفَرْجَ فَقَالَ عَلِيُّ بْنُ حُسَيْنٍ أأَنْتَ سَمِعْتَ هَذَا مِنْ أَبِي هُرَيْرَةَ؟ فَقَالَ سَعِيدٌ نَعَمْ فَقَالَ عَلِيُّ بْنُ حُسَيْنٍ لِغُلَامٍ لَهُ أَفْرَهَ غِلْمَانِهِ ادْعُ لِيمُطَرِّفًا قَالَ فَلَمَّا قَامَ بَيْنَ يَدَيْهِ قَالَ اذْهَبْ فَأَنْتَ حُرٌّ لِوَجْهِ اللهِ ﷻ

bayhaqi:12596 – Abū al-Ḥusayn ʿAlī b. Muḥammad b. ʿAbdullāh b. Bishrān> Abū Jaʿfar Muḥammad b. ʿAmr b. al-Bukhturī > ʿAbd al-Raḥman b. Marzūq Sanah Khams And Sittīn Wamiāʾatayn > Makkī b. Ibrāhīm > ʿAbdullāh b. Saʿīd b. Abū Hind > Ismāʿīl b. Abū Ḥakīm a freed slave of Āl al-Zubayr > Saʿīd b. Marjānah > Abū Hurayrah

[Machine] The Messenger of Allah ﷺ said, "Whoever frees a believing slave, Allah will free every part of his body from the Fire. He will free his hand with His Hand, his leg with His Leg, and his private parts with His private parts." Ali ibn al-Husain said, "Did you hear this from Abu Hurairah?" He replied, "Yes." So Ali said, "Pray for me to be included in the blessings of this narration." And he was one of his favorite servants. So when he stood up before him, he said, "You are free for the sake of Allah."
